I was just wondering if anyone has hooked up a boost gauge on this s/c. Reason I'm asking is I took a buddy for a ride and he was telling me I'm losing boost beaucse it didn't seem like it had power when I was nailing it at dead stop.. I was looking to install a boost gauge to see if I'm not getting all the boost that I'm supposed to be getting. I posted a 20 roll vid

Thanks

 

theres a vacuum port on the back of the blower

 

Anywhere in the lower manifold after the rotors will be fine.

 

Has anyone done it on this blower!? Also do you guys think it feels like I lost boost because I went from a 3000stall to a 2500stall!? Thanks againb

 

Log with a tuner and you'd know exactly how much boost it's running and if it's possibly down on power.

Stall speed does not change how fast the motor rev's and how much boost the blower can make. If you didn't change the pulley size or the rpm limits, the blower is not just going to make less boost unless there in a vacuum leak somewhere.

 

Ok thank you!

 

+1.

Anywhere else and it won't be accurate.

 

You could be getting belt slip, you may have high IAT's. Burst knock may be pulling timing, or maybe it's all fine. Get a gauge on it and see where it's at and take it from there. Do you have access to a scanner or anything?

 

My tensioner locked up after I launched it on auto a week or so ago but went back to normal but other then that I don't hear the belt slipping at all. What type of scanner? From the vid I posted does it seem to be performing fine???
